PDF-Abstract The presence of two sets of paired appendages

We are interested in identifying genetic systems that could have been responsible for the origin of the first set of such appendages for their subsequent duplication at a different axial level andor for the generation of their distinct identities It.

Should data from the following situation be analyzed as paired data or separate samples? Paired Data Separate Samples To study the effect of sitting with a laptop computer on one’s lap on scrotal temperature, 29 men have their scrotal temperature tested before and then after sitting with a laptop for one hour.
